A discus thrower (arm length 1.1 m) starts from rest and begins to rotate counterclockwise with a constant angular acceleration of 1.7 rad/s2. (a) How many radians of angle does it take for the discus thrower's angular velocity to reach 5.7 rad/s

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j

What’s #16 asking me and how do i solve it?

Need only answer if you think you know it
